SPRING-HEEL.

SPECIFICATION forming part of Letters Patent No. 581,661, dated April27, 1897.

Application filed June 29, 1896. Serial No. 597,432. (No model.)

To all whom if; may concern/x Be it known that I, BIRGER HEFTYE, acitizen of the Republic of Mexico, and a resident of Tuxpan, in theProvince of Vera Cruz and Republic of Mexico, have invented certain newand useful Improvements in Spring- Heels; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to improvements in spring-heels for boots andshoes, and is more particularly designed for the use of railwayemployees who are compelled to stand during the running of the cars.

It is well known to those familiar with railway matters that thevibration of the cars while in motion has an injurious effect upon thefeet of those employees who are compelled to stand for a greater part ofthe time when employed; and the object of the present invention is toprovide a spring-heel which will yield to the vibrations of the car andthus obviate any annoyance or injurious effects which would otherwise becaused by such vibrations.

The invention consists, essentially, of a metal shell comprising a plateof the general contour of the heel portion of a shoe, adapted to besecured to the sole and provided with a downwardly-extendin g flange atthe edges, a correspondingly-formed plate with an upwardly-extendingflange telescoping therein, and a series of springs interposed betweensaid plates and means for securing said plates or sections together, ashereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof a shoe provided with my improved heel. Fig. 2 is a perspective viewshowing the two sections composing the heel detached from each other andfrom the shoe. Fig. 3 is a longitudinal sectional view of the heeldetached, showing ice-creepers connected therewith.

In the said drawings, the reference-n umeral 1 designates a shoe of anyordinary or suitable construction. The numeral 2 designates the inner orupper heel-section, consisting of a metal plate of the contour or shapeof the sole at the heel, and provided with a series of screw-threadedapertures 3, through which pass screws 4, which also pass through thesole and serve to hold the section in place.

The n umeral 5 design ates the lower or outer section, of the samegeneral form as the section 2, consisting of a metal plate 6 and anupwardly-extending flange 7. which fits or telescopes in section 2, asseen in Figs. 1 and interposed between these sections are springs of anysuitable construction, coiled springs 8 being shown in the presentinstance. The ends of the screws 4 pass into the upper ends of thesprings to hold them in place. The flanges of the lower section 5, atthe front and rear, are formed with an aperture 9 for the passage ofheaded screw 10, which also passes through elongated slot 12 in theflange of section 2. This screw holds the section 5 to section 2, yetpermits it to move up and down to a limited extent.

The numeral 13 designates screw-threaded pins, (see Fig. 3,) whichengage with corresponding apertures in section 5, and serve asice-creepers. v

I generally employ to u r springs between the sections 2 and 5, but moreor less may be employed, according to the weight of the person.

The improved heel may be applied to boots now in use by knocking off theleather heels thereon and securing the former thereto, as abovedescribed.

Having thus fully described my invention, what I claim is- 1. Thecombination in a spring-heel for a boot or shoe, of the inner sectionconsisting of the plate provided with a series of screwthreadedapertures, and the flange having elongated slots, the lower sectioncomprising the plate having a flange telescoping with the flange of theupper section, the headed screws passing through said slots and securedto the flange of the lower section, the coiled springs interposedbetween said sections, and the screws passing through said upper sectionand engaging with the upper ends of said springs, substantially asdescribed.

2. The combination with a boot or shoe, the heel-section comprising theplate having a ICO series of screw-threaded apertures and the tion andengaging with screw-threaded aperfiange having an elongated slot, andthe tures in the movable section; substantially headed screws passingthrough the sole and as described. through said apertures, of themovable sec- In testimony that I claim the foregoing as l5 5 tioncomprising the plate having a flange enmy own I have hereunto affixed mysignature gaging with the flange of the upper section, in presence oftwo Witnesses. the coiled springs interposed between said 7 r T 1sections and the said screws engaging with BIRGER HEF F1 the upper endsthereof, the screw-threaded lVitnesses: 10 pins or creepers, and theheaded screws pass- I.
